7 Claims. (01. 32-14) p the lingual socket-element of Figure 6 has been Our invention relates to orthodonticappliances and more particularly to anatomically contoured anchor bands forming part thereof.

It is an object of the invention to provide. a

'5' band which is simple, inexpensive, and durable in use, and which may be accurately fitted to the teeth without injury to the gums.

A further object of the invention is the provision of bands especially adapted for attachment to the molars, both maxillary and mandibular, and shaped in conformity to the anatomical structure of the teeth.

Another object of the invention is the provision of simple and efficient means for attaching. the arch wire to.the bands, and which may be secured to the bands by spot welding.

Still another object of the invention is the provision of interchangeable means for holding the arch wires in position.

Other objects reside in details of construction and novel combinations and arrangements of parts, as will more fully appear in the course of the following description.

In the accompanying drawing, in the several views of which like parts have been similarly designated,

Figure 1 represents a plan view of the bands attached. to teeth and supporting arch wires in operative relation to the teeth,

Referring further to the drawing, the anchor bands, designated generally as M, are shown in Figure 1 attached to teeth 15, and arch wires [Band I! are supported on the bandstoex'ert the required pressure against the teeth- The bands are of two types, the band l'4aibeing provided forfuse on the maxillary molar. teeth;

and the band Mb being provided foruse on the vide a projection on its inner surface. 'Ihis'bevel and projection acts as a stop to prevent the band being forced past the bell of the molar" teeth,

the. projection engaging the buccal groovef when the band is in place on the molar.

The band Mb differs somewhat from'ban'd' I 411. in that the circumferential walls incline slightly from an upright position, in addition to the'bev eling and depressing of its upper edge as explained hereinabove. by cutting the band from seamless stock, at'ap' proximately a twelve degree bias. A projection ,(not shown in Figure 3, but similar to theflpro r jection [9 shown in Figure 5) is" fitted in' the lingual groove of the lower-molar tooth, andiprel. vents the band being forced down under the gums 20 to any appreciable degree.

The various devices used for connectingv the tie wires This inclination is efiected bands [4 with the arch wires l6 and H are pro- A flanged buccal socket-element 2|, best shown,

in Figure 4, is preferably of one-piece construction, having a hollow tubular socket 22, and flat flanges 23 extending tangentially from the socket 22. These flanges 23 are Welded to a band [4, as explained in the preceding paragraph, so that the socket 22 is disposed tangentially to the band I4, in the manner indicated in Figure 9. The arch wire I! fits in the socket 22 and adjusting nuts 34 bearing against the socket tension the wire H.

The flanged lingual socket-element 24, best shown" in Figure 6, is preferably of one-piece construction with its tubular socket 25 oval in cross; section and flat flanges 26 extending tangentially thereto. The flanges are welded to a band l4 so that the hollow interior of the socket 25 is disposed substantially parallel to the hollow interior of the band M. The socket-element 24 supports a lingual arch l6 byinserting the arch wire, bent double, into the socket 25.

When it is desired to stabilize the labial arch H, a flanged lug 21, preferably of one-piece construction, is attached to an incisor band 28. Flanges 29 project laterally from the lug for welding to the band 28, and are spaced at their intersection with the lug .2! to provide a groove 38, in: which a'tie wire 3| is inserted and held after the lug 21 is welded to the band 28, for fastening the arch wire I! to the lug El. When a double lug 32 is attached to the band in this manner,

the arch wire 1? is held in a channel 33 between the lugs 21 by wires 3| held in thegrooves.

In the use of the devices, the teeth are first examined, and the size of the anchor band l4 required to fit upon the molar teeth is determined. When the correct size has been obtained, the buccal and lingual socket-elements are welded on the band in the manner indicated. The bands l4 are then fittedon the molars, and because of their anatomical conformity, they are held in place without injury to the tissue of gums 20. The arch wires I6 and I1 are next inserted in the sockets 22 and 25 and the necessary tightening of these wires is effected. The labial arch may be stabilized on the incisor band 28, if required.

It is apparent from the foregoing that the attachment devices are easily mounted on the bands and provide a durable union which will readily withstand any pressures exerted by the arch wires.

Variations in the construction and arrangement of the constituent parts may be resorted to within the spirit of the invention as defined in the hereunto appended claims.

What we claim and desire to secure by Letters Patent is:

. 1. As an article of manufacture, an orthodontic anchor band comprising a seamless tubular band open at both ends, the planes of the upper and the lower edges being inclined with respect to the axis of the band, one edge of the band being beveled inwardly to engage a grinding surface of a tooth to which it is applied.

2. As an article of manufacture, an orthodontic anchor band comprising a seamless tubular band open at both ends, the planes of the upper and the lower edges being inclined with respect to the axis of the band, one edge of the band being beveled inwardly to engage a grinding surface of a tooth to which it is applied, the beveled edge having a portion depressed to provide a projection on the inner surface of the band to serve as a stop when the band is applied to the tooth.

3. As a new article of manufacture, an arch- Wire support for orthodontic bands comprising a single plate formed into a tube portion to receive an orthodontic arch, and oppositely disposed flanges for fastening the article to an orthodontic band, projecting tangentially from the tube, in a direction transversely of the longitudinalaxis of the tube, and in planes parallel with the axis of the tube, said portion projecting longitudinally beyond said flanges.

4. In an orthodontic device having. an archvvire, a band for application to a tooth, an anchoring device carried, by the band for connecting an arch-wire thereto, said device having a tubular socket portion for the reception of one end of the arch-wire, the anchoring device having .two flanges extending in opposite. directions from the tubular socket portion, and which serve as means for attaching the anchoring device to the band so as to form an integral unitary structure, said tubular socket portion projecting longitudinally beyond said flanges.

5. As an article of manufacturaan' orthodontic anchor band comprising aseamless tubular band open at both ends, and cut on a bias, whereby the planes of the upper and the lower edges are inclined with respect to the axis of. the band.

6. As an article of manufacture, an orthodontic anchor band comprisinga seamless tubular band open at both ends, and'cut on a bias approximating twelve degrees. from the axis, whereby the planes of the upper and lower edges are inclined with respect to the axis'of the band.

'7. As an article of manufacture, an orthodontic anchor band comprising a seamless tubular band open at both ends, and out on a bias, whereby the planes of the upper and the lower edges are in-' clined with respect to the axis of the band, one

edge of the band being beveled inwardly to engagea grinding surface of a tooth to which it is applied, the beveled edge having a portion depressed to provide a projection on the inner surface of the band to serve as a stop when the band is applied to the tooth.
